Grapevine “IASMA ECO 2”

ABSTRACT

This invention is a new and distinct grapevine variety named “IASMA ECO 2” which is characterized by producing red berries which are rounder, less sensitive to  Botrytis cinerea  and with a higher tannin content with respect to the two parents.

Latin name of the genus and species claimed: Vitis vinifera L.

Variety denomination: “IASMA ECO 2”.

CROSS REFERENCE TO RELATED APPLICATIONS

The present application is related to Community Plant Variety application 2012/2343, filed in the Community Plant Variety Office on Oct. 25, 2012, the entire contents of which are hereby incorporated by reference.

BACKGROUND OF THE INVENTION Discussion of the Background

The new and distinct grapevine described and claimed herein originated from a hand pollinated cross of the Teroldego variety (seed parent) and the Lagrein variety (pollen parent), neither of which are protected by plant patent, plant variety protection certificate, or similar. The seeds were subsequently germinated and the resulting plants were planted in the field. The present variety of grapevine was selected as a single plant, and asexually propagated by hardwood cuttings. The resulting propagules were planted and were found to reproduce true-to-type through at least three generations of asexual reproduction, with the observations taking place from 2004 to 2010 in San Michele All'Adige (TN)—Trentino Alto Adige—Italy (46° 11′ Lat. N, 11° 28′ Long. E, 235 s.l.m.).

SUMMARY OF THE INVENTION

To the inventor's knowledge, there are no varieties similar to the new variety; being a crossing result, they contain 50% of the genetic material of the seed parent and 50% of the genetic material of the pollen parent.

The present variety produces red berries which are rounder, less sensitive to Botrytis cinerea and with a higher tannin content with respect to the two parents.

The variety IASMA ECO 2 differs from the parents Teroldego and Lagrein in having no anthocyanin coloration of the apex, and in the absence of crawling and erect hairs compared to the parents which have a high density of crawling and sparse erect hair.

The young sprout of IASMA ECO 2 has no creeping or erect hairs while its parents have them in a low amount.

The tendrils of the variety IASMA ECO 2 are short, while those of its parents are long.

The young leaves of Teroldego and Lagrein have green NN155C color, and a high density of creeping hairs between the ribs, while the color of the IASMA ECO 2 leaf is green 136D. The hair density between the ribs is medium in IASMA ECO 2.

The mature leaf is large in Lagrein and Teroldego, and has three lobes, while in IASMA ECO 2 it is medium-sized with five lobes. The teeth of IASMA ECO 2 are tiny. One of their sides is concave, one side is rectilinear, as in Lagrein, but it differs from the Teroldego which has convex teeth. The teeth of the parents are medium sized.

The petiole sinus is Brace shaped in the IASMA ECO 2 variety, while in Teroldego it is open V-shaped and open U-shaped in Lagrein. The base of the lateral sinus is V shaped in the parents while in IASMA ECO 2 it is U-shaped and has one tooth. The density of prostrate hairs and of erect hairs between the ribs is high in the parents, and medium and low in the variety IASMA ECO 2.

The section of woody shoot is circular in Teroldego and Lagrein and in IASMA ECO 2 it is elliptic.

The first inflorescence of variety IASMA ECO 2 is on the second node. Its basal bud (1-3) fertility is very high, while insertion of the first inflorescence in Lagrein is at the 3rd and 4th nodes, with medium fertility of the buds; in Teroldego the first inflorescence is at the 5th internode with very low bud fertility. The number of inflorescences per shoot is 1.1 to 2 in the parents and 2.1 to 3 for the variety IASMA ECO 2.

The first inflorescence of IASMA ECO 2 is about 15 cm long and the date of full bloom is generally around June 10, while Lagrein has 15 cm inflorescence, and a date of full bloom in 7th June. The first inflorescence of Teroldego is 20 cm long and the date of full bloom is 7th June.

The cluster of IASMA ECO 2 is very long (>24 cm), medium width (<12 cm) and loose, while Teroldego shows a cluster of similar size but very compact, while in Lagrein the bunches are compact and their length is between 16 and 24 cm and <12 cm broad.

The IASMA ECO 2 berry is elliptic, and narrow (<13 mm) with the hilum barely visible. The flesh is soft, and the length of pedicel is short (<7 mm). In Teroldego and Lagrein the berry width is 13-18 mm, the hilum is visible, the pulp is firm, and the pedicel short.

The vesting period of IASMA ECO 2 is later than that of its parents.

FINDINGS OF MOLECULAR INVESTIGATIONS

DNA was extracted from young leaves of different accessions for each variety by using the Doyle and Doyle extraction method (1990) as modified by Grando et al. (2003). Molecular markers were obtained by analyzing DNA specimens at the 9 microsatellite loci specified by the European projects named Gen-Res81 and Grape-Gen06 for vine variety characterisation and at locus VMC1B11 (Vitis Microsatellite Consortium). In particular, the primers and amplification conditions described by Thomas and Scott (1993) for locus VVS2, Bowers et al. (1996) for loci VVMD5 and VVMD7, Bowers et al. (1999) for loci VVMD25, VVMD27, VVMD28 and VVMD32 and Sefc et al. (1999) for loci VrZAG62 and VrZAG79 were applied. PCR products were separated and analyzed with the Genetic Analyzer ABI3130 and the GeneMapper® v4.0 software.

CULTIVATION CHARACTERISTICS AND SUITABILITY

The present invention vine variety shows medium vigour with early sprouting stage, with blue-black, medium-small, spherical berry with medium thickness skin. The bunch is medium-sized, winged, cylindrical and slightly straggly. It has a medium yield and is relatively resistant to botrytis. Its physiological maturity occurs in the third stage; it shows an excellent capacity to accumulate sugars while preserving medium-high acidity values. It can perfectly stand winter cold and shows a good resistance to downy mildew and powdery mildew. It prefers fertile hilly soils.

USE

The present invention vine variety is suited to produce both young and medium-long aged red wines. Young wines have a fruity taste (morello cherry and currant bush). When aged, spicy flavours become more accentuated; it shows a good acid resistance, also in case of small crops and particularly warm vintage years. The wines obtained from this vine variety show an excellent and deep ruby colour, good body, medium-high alcohol content, good tannin content, excellent texture and medium acidity. It is suitable to produce both young and medium-long aged wines; ageing and maturing create the typical character of noble red wines with spicy flavours and pleasant tannicity. It can also be successfully be used to cut other wines.
